''J Improved Lighted Traffic Sigxt for TraftSc Control 'TECHNICAL FIELD OF THE INVENT14N
The invention relates to apparatuses for use during waffic conwoi, and more particularly, to an improved lighted traffic sign having an adjustable and portable seat, a portable urinal having an enclosure, a liquid applicator and a sign and warning device for use during controlling traffic.
:DESCRIPTION OF T'~iE RELATED ART
Traffic control is very important, especially at consauction sites where workers are laboring in close proximity to moving vehicles. As the interstate highway system ages, more repair and construction is being performed at locations where the speed limit is very high. Accordingly, it is important to give motorists warning of the construction area as soon as possit~le. It is desirable that the warning be visible even under poor visibility conditions. It is also desirable that the warning alert motorists even when there may be other distractaons. It is also desirable that the warning device be as versatile and mtati-:functional as possible. Finally, workers are not free to Ieave their workstation even in times of personal necessity, so it is important to have devices to accc~xnmodate the 2o workers' personal needs at the workstation.
Lighted sign structures ara used to warn motorists. The use of lighted sign structures is known in the prior art. Examples include Unittd States Patent No.
6,150,957, issued November 21, 2000, to Heinz et al.; United States Patent No, 4,042,919, issued Aug. 16, 1977, to Patty; United Statas Patent No. 5,276,424, issued Ian. 4, 1994, to Hegemann; United States Patent No. 5,094,1.10, issued Dec. 2, 1997, to Clifford; and United States Patent IVo.~5,68'~,500, issued Nov. 18, 1997, to Lamparter. The first is a lighted sign and warning device. The next three are hand-held signs and, as such, their battery capacity is linuted. The last is mounted on a school bus and uses the bus' power supply; however, it is not usable at a construction site.

6,150,957, issued November 21, 2000, to Heinz et al.; United States Patent No, 4,042,919, issued Aug. 16, 1977, to Patty; United Statas Patent No. 5,276,424, issued Ian. 4, 1994, to Hegemann; United States Patent No. 5,094,1.10, issued Dec. 2, 1997, to Clifford; and United States Patent IVo.~5,68'~,500, issued Nov. 18, 1997, to Lamparter. The first is a lighted sign and warning device. The next three are hand-held signs and, as such, their battery capacity is linuted. The last is mounted on a school bus and uses the bus' power supply; however, it is not usable at a construction site.
The problem with many of these devices is that they do not allow wind to pass through the sign, which is difficult to handle during windy conditions.
The Hean~ Patent allows wind to pass through the sign, but during gunny days, the light shines through making it difficult for motorists to read the. sign.
'1~he workers using these signs and warning devices for controlling traffic are not free to leave their workstation even in times of personal necessity.
For example, a worker is not allowed to leave a traffic control sigr. unmanned to use the restroom. The consequences of an unmanned traffic contra}1 sign could be devastating.
The present invention is directed to overcoming one or more of the problems set forth above.
An aspect of the present invention is to provide apparatuses for use during traffic control which overcome one or more of the about described deficiencies.
In another aspect of the invention, there is provided a s;,gn and warning appaxatus for controlling traffic having slots and inserts therei:~ to allow wind to pass through the sign and warning apparatus while precluding light from passing through, In another aspect of the invention, there is provided a spat apparatus for a person to rest or lean against during long periods of standing.
In yet another aspect of the invention, there is providec. an applicator for applying liquid to wheels or tires of a device to preclude the accumulation of asphalt, tar or other matter during movement in construction.
In still another aspect of the invention, there is providc:l a portable restroom apparatus for use while simultaneously controlling t°affic so that the worker does not have to leave the workstation.
In yet another aspect of the invention, there is provided a restroom enclosure apparatus for use with the portable re~stroom apparatus to provide privacy.
3l16 The above aspects are merely illustrative examples of a few of the innumerable aspects associated with the present invention and should not be deemed an all-inclusive listing in any manner whatsoever.

Figs. 1, la, and 1b illustrate a sign and warning device 'l0 used to warn approaching motorists to areas of construction or repair. 'T'he ,ign and warning device 10 is an improvement of United States Patent No. 6,150,957, which is hereby incorporated by referene~.
The sign and warning device 10 includes a two-facet. sign I 1 supported on an extendable telescoping pole 13, and a high intensity quit flashing strobe light 12 encased in an omnidirertional housing 14. The two-faced sign 11 can be removed from the extendable telescoping pole 13. The hou.;ing 14 contains a metal plate 16, which reflects the strobe light outwardly and downwardly. The light is reflected outwardly to project the light at a great distance to alert motorists and oncoming traffic. The light is reflected downwardiy to illuminate the face of the two-faced sign 11 which helps to call attention to it and to make it more recognizable and readable. Moreover, the light is reflected cmtwardly and downwardly to provide a work light at night. The housing 1 ~ as mounted at the top of the two-faced sign x x and the light 12 is plugged into a receptacle (not shown) to connect it to DC power. This upper receptacle is ~:onnected to a receptacle (not shown) near the bottom of the extendable telEacvping pole 13 by a spiral electrical cord which is enclosed in the extendable telescoping pule 13. A
battery (not shown), advantageously a rechargeable 12 volt, ~i00 amp., deep cycle marine-type battery, is connected by a wire with an electrical plug (not shown) to this receptacle (not shown), thus providing power for the light.
The two-faced sign 11 is formed by two vented octagonal sheets 11 a, l 1b which are joined by a plurality of 3/4 inch nylon spacers (not shown).
Typically one sheet has one message or indicia, such as "STOP," and die other sheet has another, such as "SIfOW." The sheets 11a, 11b have slots 2~., which are advantageously horizontal as shown in Fig. 1 a. The purpose of the slots 22 is to decrease wind resistance. The slots 22 have inserts 15 that az~e positioned such that a horizontal viewing line is blocked. The inserts 15 can '.,e of various configurations; however, in the preferred embodiment, the in ~erts 15 are substantially "z" shaped. The inserts IS can be made out of the sheets of metal that are cut to make the slots 22. For example, the material rc;moved can be bent or formed to make the inserts 15. The inserts 15 rnay also be plastic and manufactured using an injection molding technique. The inserts 15 are placed between the two-faced sign 11 and attached thereto. In the preferred embodiment, the inserts 15 are riveted; however, there are many fastencx means known to those skilled in the art that can substituted for the rivets. The slots 22 Fellow wind to pass through the two-faced sign 11, while the xnsercs 15 preclude sun light from passing directly horizontal through the two-f:iced sign 11. The inserts 15 assist motorist by blocking sun light that slvnes through the slots impairing their ability to read the sign. 'The inserts 15 above: the message or i ndicia are mounted such that the wind passes upwardly as shown in Fig. 1 by arrow A. Conversely, the inserts IS below the message or indicia are mounted such that the wind passes downwardly as shown in Fig. 1 by arrow B. The slots I o 22 decrease wind resistance, while the inserts 15 preclude si n light from shining directly horizontal through the slots 22. This combination is beneficial.
Referring now to Figs. 2, 2a, and 2b, an adjustable, p~srtable seat device 30 having a seat 31 is illustrated. The seat 31 is similar to a bicycle seat in the preferred embodiment; however, there are various seat desig«s that can be substituted. The seat 31 is operatively attached to a bar 32 having holes 33 for rf.ceiving a pin (not shown). The bar 32 slips around or batv~~een a lower bar having holes 33 for receiving a pin (not shown). The bar 32 and the lower bar matt such that the holes 33 align in at least one place. The pin is placed through the holes 33 in the bar 32 and the lower bar 34, thereby sattir~g the height of the seat 31. The lower bar 34 has a resilient means 35 operative: y attached thereto.
In a preferred embodiment, the resilient means is a spring, but it may also be a pneumatic, hydraulic or gas-charged shock absorber. The re;;ilient means 35 reduces the rigidity of the seat device 30 for comfort. The lower bar 34 has a non-skid pad 36, which is preferably made of rubber. The nc~n-skid pad 36 provides a non-slip surface between the seat device 30 and th a ,ground or resting surface.
The seat device 30 can be used by people that stand fcr long periods of time to take stress off of the lower back and feet. In one example, construction or nviffic workers utilize the seat device 30 while eontrolliz3g traff c. The desired height is ascertained and set by aligning the holes 33 of the bavr~ 32 and the lower bar 34 and placing the pin through the holes 33. The workar loans against the seat device 30 to take the stress off of the lower back. The resilient means provides comfort to the worker. The worker is able to hold a traffic control sign or control mechanism for an automated traffic control sign while Leaning or restiztg against the seat device 30. Moreover, the worker can quickly move away from the scat device 30 in case of an emergency. For exaayple, if a car is coming towards the worker, the worker may instantly stop leaning against the seat device 30 and rapidly move out of the way. In contrast, if a car is moving towards the worker sitting on a chair or stool, the worker would first have to stand up.
The additional time to stand may mean the difference between injury and well-being.
Referring now to Figs. 3, 3a, 3b, and 3c, a liquid apf~licator device 40 is shown having a reservoir 41 fox storing liquids. The reservoir 41 has a cap or opening 42 for receiving liquids. The licLuid applicator dev: ce 40 is used in conjunction with the sign and warning device 10 described above or for similar sign and warning devices known to those skilled in the art i r~ conjunction with a 1>ase 60, shown best in Fig. 5a. The base 60 is similar to the; one described in United States Patent No. 6,150,957, which was previously i ncorporated by reference and no further explanation is therefore required. '.Che base 60 has wheels 61, which are preferably rubber. The reservoir 4I is located above the wheels 61. A line 43 operatively conneeas the reservoir 41 io a removable applicator pad 44 mounted partially around the diamEter of 'he wheels 61. The line 43 transfers the liquid from the reservoir 41 to the applicator pad 44, The applicator pad 44 may be removed when not needed, such a;a when the sign and warning device 10 is used in general road construction. A valve 45 is operatively connected between the reservoir 41 and the applicator pad 4, ~. for controlling the flow of liquid from the reservoir 41. The valve 45 is adjustable to regulate tha flow of liquid from the reservoir 41 and can be completely cpened or closed as die case may be.
'The reservoir 41 is filled with Iinsted oil, citrus plus, terpene or other liquids that preclude asphalt, tax or other material from accw~nulating on the ~~~ wheels 61 of the base 60 when the base 60 is moved from one: location to another.
In a preferred crrtbodiment, the liquid from the reservoir 41 flows downwardly to the applicator pad 44 due to gravity. In another embodiment, 'the liquid is transferred from the reservoir 41 to the applicator pad 44 through means of a pump 46. The pump 46 can be mechanical or electrical. Ip Fig. 3, a mechanical hand pump 46 is shown.
Fig. 3c illustrates an embodiment where the wheels 61 are pivotally mourned on the base 60. The line 43 is operatively connected to a fitting 47.
The fitting 47 is operatively connected to the base 60. The base 6t) includes a hole so to that the iiguid may pass from the line 43 through the fitting 4;' and the base 60 to the applicator pad 44.
Figs. 4 and 4a shows a portable rcstroom facility 50 having a urinal 51 for receiving urine. The urinal 51 is operatively attached to an extension device 52.
The extension device 52 is operatively attached to a swivel 53, The extension device 52 can be extended aR shown in Fig. 4a or retracted tov~jaxd the swivel 53.
The: swivel 53 is used to pivot the extension device 52 and the urinal 51 about an axle 54 of the swivel 53. The extension device 52 and the swi ~~el 53 is operatively attached to a frame SS of the base 60.
The urinal S 1 has a n~be 56 operatively attached thereto, wherein urine is received in the urinal 51 and flows through the tube 56 to a waste tank 57.
The tube 36 is attached to the extension device 52 and the frame 5~~ by fasteners 58.
The waste tank 57 receives and stores the urine received from the tube S6. The waste tank 57 is removably mounted to the frame 55 so that it ; an be removed and emptied at convenient times by removing a waste cap 59.
Fig. 5a shows the base 60 having the pole 13, which is t~ttached to the two-faced sign 11 or other sign. A restroom enclosure 65 is provided having a curtain 66. The curtain b6 is operatively attached to an extension frarr~~ 6?. The extension frame 67 has arms 68, preferably four as shown in F:~g. 5b. The arms 68 Fue Operatively connected together by pins ?0. In the preferred embodiment, one of the pins 70 is removable so that the arms 68 can be folded as shown in Fig.
Sc during non-use, The extension frame 67 is operatively attached to a height adjustment or raising/lowering device 69. The height adjustment device 69 is used to lower and raise the extension frame 6'7 and the curt;~in 66 to a desired height while a person uses the portable restroom facility SO shown in fiig. 4 and described above. The height adjustment device 69 can be ntade from various designs; however, in the preferred embodiment, a triangulate shaped bracket slides up and down a pin. These types of devices are known to th~ase skilled in the art and no further explanation is required, Referring in jointly to Figs. 4, 5a, 5b and 5c for oper;ttionai purposes, a person in need of urinating pulls the extension device 52 outwardly, horizontally away from the base 60. The person positions himself in fro:rat of the urinal 51 and thereafter positions the extension frame 67 around his body fastening the pin 70.
The curtain 66 is positioned around the person and the height of the height F~djustnnent device 69 is adjusted to the appropriate height. 'thereafter, the person has privacy during urination. During times when a person cannot be found to replace another person controlling traffic, the person control ling traffic can simultaneously use the portable restroom facility 50 and control traffic by holding the sign. Alternatively, the person does not have to leave the workstation to use a remote restroom and can use the portable restroom facility 50 during non~active times. The portable restroom facility 50 and the restroom enclosure 6S are ideal when a person is not able to leave the workstation.
After use, the extension frame 67 is folded up as shov~n in Fig. 5c by removing the pin 70. The extension device 52 is pushed inwardly towards the base 60. The waste tank 57 can be emptied at a convenient ~,ime.
Deferring now to Fig. 6, a push bar handle 80 can be incorporated into the device, which was incorporated by reference. The push bar handle 80 ca,n be improved by incorporating a hinge system 82, which allows the push bar handle to be folded down after the pole 13 is removed for transport;~t9on. The push bas handle 80 is an improvement over disassembling and removing the push bar handle 80 for transportation. There are many hinge systems ~2 that are known to those spilled in the art that can be incorporated with tho push bar handle.
The hinge system 82 is locked into place through the use of pins 84. In a preferred f~mbodiment, rwo pins 84 are used but one skilled in the art rnay recognize only one pin is necessary. Moreover, in the preferred embodiment, cables 86 attach the pins 84 to the push bar handle 80.
The apparatus of the present invention arc not confined to the embodiment described, but can bE used on any agricultural machines to obtain the effects according to the invention. Other aspects, objects and adva~atages of the present invention can be obtained from a study of the drawings, the disclosure and the to accompanying claims. The invention in its broader aspects :.s nvt lirnitcd to the specific steps and apparatus shown and described but departures may be made tlaerefrom within the scope of the accompanying claims witr~out departing from the principles of the invention and without sacrificing its chief advantages.
The Hean~ Patent allows wind to pass through the sign, but during gunny days, the light shines through making it difficult for motorists to read the. sign.
'1~he workers using these signs and warning devices for controlling traffic are not free to leave their workstation even in times of personal necessity.

Figs. 1, la, and 1b illustrate a sign and warning device 'l0 used to warn approaching motorists to areas of construction or repair. 'T'he ,ign and warning device 10 is an improvement of United States Patent No. 6,150,957, which is hereby incorporated by referene~.
The sign and warning device 10 includes a two-facet. sign I 1 supported on an extendable telescoping pole 13, and a high intensity quit flashing strobe light 12 encased in an omnidirertional housing 14. The two-faced sign 11 can be removed from the extendable telescoping pole 13. The hou.;ing 14 contains a metal plate 16, which reflects the strobe light outwardly and downwardly. The light is reflected outwardly to project the light at a great distance to alert motorists and oncoming traffic. The light is reflected downwardiy to illuminate the face of the two-faced sign 11 which helps to call attention to it and to make it more recognizable and readable. Moreover, the light is reflected cmtwardly and downwardly to provide a work light at night. The housing 1 ~ as mounted at the top of the two-faced sign x x and the light 12 is plugged into a receptacle (not shown) to connect it to DC power. This upper receptacle is ~:onnected to a receptacle (not shown) near the bottom of the extendable telEacvping pole 13 by a spiral electrical cord which is enclosed in the extendable telescoping pule 13. A
battery (not shown), advantageously a rechargeable 12 volt, ~i00 amp., deep cycle marine-type battery, is connected by a wire with an electrical plug (not shown) to this receptacle (not shown), thus providing power for the light.
The two-faced sign 11 is formed by two vented octagonal sheets 11 a, l 1b which are joined by a plurality of 3/4 inch nylon spacers (not shown).
Typically one sheet has one message or indicia, such as "STOP," and die other sheet has another, such as "SIfOW." The sheets 11a, 11b have slots 2~., which are advantageously horizontal as shown in Fig. 1 a. The purpose of the slots 22 is to decrease wind resistance. The slots 22 have inserts 15 that az~e positioned such that a horizontal viewing line is blocked. The inserts 15 can '.,e of various configurations; however, in the preferred embodiment, the in ~erts 15 are substantially "z" shaped. The inserts IS can be made out of the sheets of metal that are cut to make the slots 22. For example, the material rc;moved can be bent or formed to make the inserts 15. The inserts 15 rnay also be plastic and manufactured using an injection molding technique. The inserts 15 are placed between the two-faced sign 11 and attached thereto. In the preferred embodiment, the inserts 15 are riveted; however, there are many fastencx means known to those skilled in the art that can substituted for the rivets. The slots 22 Fellow wind to pass through the two-faced sign 11, while the xnsercs 15 preclude sun light from passing directly horizontal through the two-f:iced sign 11. The inserts 15 assist motorist by blocking sun light that slvnes through the slots impairing their ability to read the sign. 'The inserts 15 above: the message or i ndicia are mounted such that the wind passes upwardly as shown in Fig. 1 by arrow A. Conversely, the inserts IS below the message or indicia are mounted such that the wind passes downwardly as shown in Fig. 1 by arrow B. The slots I o 22 decrease wind resistance, while the inserts 15 preclude si n light from shining directly horizontal through the slots 22. This combination is beneficial.
Referring now to Figs. 2, 2a, and 2b, an adjustable, p~srtable seat device 30 having a seat 31 is illustrated. The seat 31 is similar to a bicycle seat in the preferred embodiment; however, there are various seat desig«s that can be substituted. The seat 31 is operatively attached to a bar 32 having holes 33 for rf.ceiving a pin (not shown). The bar 32 slips around or batv~~een a lower bar having holes 33 for receiving a pin (not shown). The bar 32 and the lower bar matt such that the holes 33 align in at least one place. The pin is placed through the holes 33 in the bar 32 and the lower bar 34, thereby sattir~g the height of the seat 31. The lower bar 34 has a resilient means 35 operative: y attached thereto.
In a preferred embodiment, the resilient means is a spring, but it may also be a pneumatic, hydraulic or gas-charged shock absorber. The re;;ilient means 35 reduces the rigidity of the seat device 30 for comfort. The lower bar 34 has a non-skid pad 36, which is preferably made of rubber. The nc~n-skid pad 36 provides a non-slip surface between the seat device 30 and th a ,ground or resting surface.
The seat device 30 can be used by people that stand fcr long periods of time to take stress off of the lower back and feet. In one example, construction or nviffic workers utilize the seat device 30 while eontrolliz3g traff c. The desired height is ascertained and set by aligning the holes 33 of the bavr~ 32 and the lower bar 34 and placing the pin through the holes 33. The workar loans against the seat device 30 to take the stress off of the lower back. The resilient means provides comfort to the worker. The worker is able to hold a traffic control sign or control mechanism for an automated traffic control sign while Leaning or restiztg against the seat device 30. Moreover, the worker can quickly move away from the scat device 30 in case of an emergency. For exaayple, if a car is coming towards the worker, the worker may instantly stop leaning against the seat device 30 and rapidly move out of the way. In contrast, if a car is moving towards the worker sitting on a chair or stool, the worker would first have to stand up.
The additional time to stand may mean the difference between injury and well-being.
